The Tamiya 95074 HG Lightweight 19mm Aluminum Ball-Race Rollers are a practical upgrade for Mini 4WD pilots who want lighter rotating parts without sacrificing reliability. Constructed from light aluminum and ringless for minimal mass, they offer roughly a 30% reduction in weight compared to standard rollers. Equipped with 520 ball bearings, they promote low-friction rotation for cleaner runs.
Compatibility covers all Mini 4WD and Mini 4WD PRO chassis, though certain chassis layouts or body shapes may demand minor fitting tweaks. The kit ships with attachment screws to make mounting quick and secure. Ideal for racers refining setup on tight or twisty tracks, these rollers help reduce lap times through better momentum retention.
